CES Transactions on Electrical Machines and Systems, 2023 The most critical obstacle for four-wheel independently driven electric vehicles (4WID-EVs) is the driving range. Being the actuators of 4WID-EVs, motors account for its major power consumption. In this sense, by properly distributing torques to minimize

Experimental Biology and Medicine, 1950 Summary“Cell poor” and “cell rich” sweat samples from 25 normal subjects have been analyzed (total of 118 determinations). The iron content of “cell poor” sweat was negligible. On the other hand “cell rich” sweat contained a high concentration of iron.

A best-fit model of power losses in cold rolled-motor lamination steel operating in a wide range of frequency and magnetization [PDF]
, 2007 A procedure is described for identifying a mathematical model of core losses in ferromagnetic steel based on a minimal amount of experimental data. The new model has a hysteresis loss multiplicative coefficient variable only with frequency, a hysteresis ...

Experimental Biology and Medicine, 1978 SummaryMeasurements have been made of the decrease in specific activity of radioiron in circulating red cells of eight animal species. From these data calculations of body iron turnover have been made and establish a general inverse relationship between body size and rate of external iron exchange.

Stochastic Jiles-Atherton model accounting for soft magnetic material properties variability [PDF]
, 2013 Industrial processing (cutting, assembly…) of steel laminations can lead to significant modifications in their magnetic properties. Moreover, the repeatability of these modifications is not usually verified because of the tool wear or, more intrinsically,
